Psi: A-Z Guide to the Subjective Side

Can we classify paranormal experiences like mental disorders?
Imagine you're a researcher studying reports of people who claim to have out-of-body experiences. One person describes floating above their hospital bed during surgery, another talks about leaving their body during meditation, and a third mentions similar sensations during an epileptic seizure. For decades, scientists have lumped all these accounts together under the same category, but what if they're actually describing completely different phenomena? Researcher Vernon Neppe realized this mixing of apples and oranges might be why paranormal research has struggled to find consistent patterns.
Researchers propose a new system to categorize anomalous experiences more precisely.
This study proposes that paranormal research needs a detailed classification system—like medicine's diagnostic manual—to stop mixing fundamentally different experiences together.
Key Findings
The study presents a theoretical framework for standardizing the description and classification of anomalous experiences rather than empirical findings about psi phenomena.
What Is This About?
Development of a new classification system (SEATTLE) modeled on psychiatric diagnostic manuals to categorize anomalous experiences using 26 detailed descriptive levels.
Presents a comprehensive framework for classifying psi phenomena to improve research consistency and prevent inappropriate grouping of different types of experiences.
How Good Is the Evidence?
This is a theoretical/methodological paper proposing a classification framework rather than an empirical study. It was not pre-registered (meaning no analysis plan was filed beforehand) as it presents a conceptual framework rather than data analysis. No experimental controls, blinding, or statistical effects are involved since this is a methodological proposal. The paper has received 7 citations, suggesting modest academic interest. Published in NeuroQuantology, a journal that focuses on consciousness and quantum approaches to neuroscience.
This is purely theoretical work without empirical validation or testing of the proposed classification system. The paper lacks data demonstrating the reliability, validity, or practical utility of the SEATTLE framework. The shift toward subjective phenomenology may actually move further away from scientific objectivity rather than toward it.
Mainstream: Classification systems are useful tools but don't validate the phenomena being classified. Moderate: Better categorization could help identify genuine patterns in anomalous experiences. Frontier: Detailed classification is essential for advancing scientific understanding of psi phenomena.
To validate this classification system, researchers would need to demonstrate its reliability (different raters classify the same experiences similarly) and validity (the categories correspond to meaningful differences). This study presents the framework but doesn't test its practical utility or accuracy.
This paper attempts to motivate researchers to apply detailed multi-axial evaluations of spontaneous, experimental and induced anomalous experiences.
Stance: Mixed
What Does It Mean?
This researcher essentially created a 'periodic table' for paranormal experiences—a systematic way to organize phenomena that have puzzled humanity for millennia. The ambition to bring the same rigor that revolutionized psychiatry to the study of consciousness anomalies is both audacious and potentially groundbreaking.
Classification systems in science must be tested for reliability and validity before they can be considered useful research tools.

What This Study Claims
Methodology
The classification system is modeled on the American Psychiatric Association's multi-axial Diagnostic and Statistical Manual (DSM)
strongThe SEATTLE classification system applies 26 detailed phenomenological descriptive levels (A-Z) for evaluating anomalous experiences
moderateInterpretations
Spontaneous anomalous experiences are often inappropriately bundled together based on brief common descriptions despite being phenomenologically and etiologically distinct
weakThis approach implies a conceptual shift away from attempted objectification of psi phenomena to detailed analysis of specific characteristics and events
